CARDlNG-ENGINE.

SPECIFICATION forming part 0f Letters Patent No. 718,261, dated January 13, 1903.

Application filed November 15, 1900- Serial No. 36,545- (No model.)

To aZZ whom it may concern.-

Be it known that I, GUILLAUME LAURENCY, engineer, a subject of the King of Belgium, residing at Brussels, Belgium, have invented certain new and useful Improvements in or Applicable to Carding-Engines, of which the following is a specification.

My invention has for its object to enable machines for opening, carding, or combing filaceous materials to lay the fibers or filaments parallel bya special combing and drawing operation between teeth of cards or combs, to withdraw the material operated on from between these teeth without disturbing the parallelism of the fibers, and to thus produce combed, semicombed, or carded yarns of all numbers without any further manipulation than is required in ordinary carding.

My invention essentially consists in a special combination of rollers clothed alternatively with elastic material and with cardteeth and of troughs in which the said rollers rotate.

In order to have my invention fully understood, I will describe the same with reference to the annexed drawings, which show by way of example two applications of my invention.

In the drawings, Figure 1 is a sectional elevation illustrating the application of three rollers to an ordinary carding-engine. Figs. 2 and 3 are similar views illustrating the application to a carding-cylinder of one pair of rollers combined so as to allow of dividing the fleece coming from the said carding-cylinder into strips or ribbons to form slivers or preparation yarns in rotary rubbers. Figs. 4, 5, and 6 are three views of details of the divider combined with the detaching or first roller of the pair of rollers shown in Figs. 2 and 3.

The carding-engine to which the invention is applied in the case of Fig. 1 is represented by a part of its large or carding cylinder 1 and the part of the frame 2 on which is usually placed the doffer-comb, having saw-teeth, which causes the fleece to fall from the cylinder .1, from which it is wound in superposed layers either upon a roller or upon an apron 3, in which it forms a layer.

The rollers 4 and 9 are clothed with leather or other similar elastic material provided with grooves or channels. Roller 8 is clothed with card-teeth. The three rollers rotate in frictional contact each in a recess or trough 5 in the same direction, but at progressivelyincreasin g speeds-that is to say, roller 8 turns faster than the roller 4 and the roller 9 faster than the roller 8.

The material is brought by the carding-cylinder 1 to the point 6, where it is nipped by the roller 4, which causes it to slide into the trough 5,as indicated by the dotted line 7,until reaching the front of roller 8. As the said roller 8 turns faster than the roller 4, its cardteeth slide between the fibers of the fleece, which is drawn and combed simultaneously. During thiscombing operation the layer or fleece is carried along by the roller 8 and delivered to the roller 9, which, turning faster than the teeth of roller 8, draws againthe fibers, subjecting them to a new combing operation between the teeth of the roller 9. By the use of these rollers alternatively clothed with an elastic material and with card-teeth the combing action is efiected alternatively in two opposite directions, the teeth of the roller 8 combing first the fleece while drawing it forward as it is delivered from the rollerd and combing it backward when the fleece is drawn by the roller 9. It will be consequently understood that between the rollers 4 and 8 the fleece is combed by the teeth of the roller 8 sliding between the fibers of the fleece,while, on the contrary, between the rollers 8 and 9 the fibers slide between the said teeth. These rollers, alternatively clothed with elastic material and with card-teeth, may obviously be more or less numerous,according to the combing action which it is desirable to obtain. When discharged from the last roller,the material passes on to the apron 3,Where it forms a layer in the known manner. The roller 10 prevents the fleece from winding around the last roller 9. v

As shown in Figs. 2 and 3, the employment of the roller 4 allows of immediately dividing the fleece detached from the carding-cylinder,

with a view of forming therefrom slivers or preparations of yarns for spinning-frames. In

cumfer'ence; but cylinder 11 is provided with projecting portions 12, Fig. 4, which turn with friction in grooves or recesses 13, Figs. 5 and 0, made in the part of the trough 5 which partially envelops the roller 11. These recesses 13 communicate, by means of openings 14, with the recess in which the roller 4: rotates, so that at the place where th ese openings 14 are situated the projections 12 of the roller 11 pass very near the roller 4: without touching it.

By observing the direction of rotation of the rollers and 11 (indicated by the arrows 15 and 16) it will be understood that the parts of the fleece which are conducted from the carding-cylinder l by the roller & above the recesses 13, and consequently in front of the openings 14, are seized and carried away by the projections 12 of the roller 11, which draw them in the direction of the arrow 16, while those which pass between the openings 14:, not having ceased to be held against the roller 4, only leave the latter in order to enter the rotary rubbers 17, when they are completely separated from those which follow the roller 11.

The parts of the fleece which correspond to the openings 14:, and consequently to the clothed projections of the roller 11, are conducted by the latter to the rotary rubbers 18, where they are rolled or rubbed in the known manner, and the parts of the fleece remaining on the roller 4: are conducted to the ro-' tary rubbers 17.

I would remark that with the special arrangement of combing and drawing apparatus combined with the divider I obtain yarns similar to those produced by the ordinary combing process, although requiring in the manufacture no more work than ordinary carded yarns.

Having thus described my invention, What I claim is- In a carding-machine in combination with the carding-cylinder, a pair of rollers 4t 11 the first one of which being clothed over its entire surface with an elastic material and the second one being clothed on projecting portions 12 with the said elastic material a trough in which the said rollers rotate and openings in the said trough through which the projecting portions of the second roller pass so as to seize the parts of the fleece conducted by the first roller 4 above the openings of the trough, substantially as described and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GUILLAUME LAURENCY.
